a few things can cause cough...the start of puenomia, allergies, dust from hay or feed and lung worms...
Take his temp to see if that is normal...101.5-103.5 is normal range..
with the mucus in his poop...try this trick goathiker taught us..gather some poop and tie it up in a small square of gauze, float in a cup of water several hours or over night...if its lung worms you will see them or the larve floating in the water....I would choose Valbazen or Ivomec plus to treat them if you find worms...Valbazen is 1 cc per 10# orally and Ivomec is 1 cc pr 40# sub q which does sting...for your boys I would go with valbazen
treat both boys
